I actually just re-re-financed the property again last week and appraised at $230k for a better long term i% 30yr note and was able to pull out in essence all of my remaining cash in the deal and more!

Thanks in advance for your time.I have a rental property that I purchased in 2018 and rented it out until July 2019, when the tenants moved out, and the apartment remained vacant for the remainder of 2019.

The assumption is if a person has $100K to spend they could theoretically but 4-5 houses (costing  around $100K each)  since they could put down 20% on home and finance the remaining 80%.   

You are tying up more of your money in the property (3.5% vs 25%). 

Financing at 20% will tie up a lot of cash.

For a $100 fee we could lock it into a 30 year for 4.5%, but it would remain on the HELOC.

Is it wise to tie up this much cash or is it recommended to wait for another property?

The idea of tying up $50K for the prospect of earning a net 10% return of $5K isn't an attractive way to build and scale a portfolio.

Is it worth leveraging my personal residence(hopefully for 6 months or less), paying less out of pocket, and making 2k more or should I leave my residence out of it make a little less and have more money tied up for 6 months?

(The reason I would like to build is that in the market I've been looking a 90's 6bed 3bath 2 car duplex is selling for 280-290$)Keeping the remained to either pay off debt or go to auction to look for the next fixer upper.
